Good example, but you can use PrintWriter and println()-methode (line 61). Then the code would be a little bit clearer...
ReplyDeletehello,
DeleteThx for your advice.
But I want to display in the application window, for easy capture and show in the picture.
This is not a good example. You should use NIO.2.
